Local Environmental Conditions
Most of the area around this site in Westchase is woodland, with a good deal of open grassland. With Lake Julia nearby, lakeside vegetation along its shore contributes to the local mix. Common allergenic trees nearby include oak and maple. Beyond the trees, grasses matter a great deal, and pigweed is the main weed source.
Tree pollen peaks in early spring, when the weather warms to around 20°C and oak and maple are in full flower. Grasses take over in early spring and keep pollen in the air into mid-fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Mold spores join in from early summer into early winter, when damp, warm spells let them thrive.

Does pollen in Westchase come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Westchase based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Westchase, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
